SH2-234 (IC-417) in HaRGB

This is IC-417 (a.k.a. SH2-234) composed of about 5-1/2 hours of RGB and 4 hours of Ha, taken in late November and early December. Your basic emission nebula: hot stars, lots of excited gasses, 10k light-years away in Auriga.

I'm not sure how I feel about the stars. Lately it seems like star bloat with the brightest stars in RGB has been over-powering. Not sure if it's over-exposure, or the filters, or the scope or the camera, but it just doesn't seem like they should swell up so much. Someone suggested haze or fog, but it's been happening over a long period of time in an area not known for either. It seems like I should be able to control them better, but can't. Any tips or suggestions here would be appreciated.

The refractors!

The “AstroBin Image of the Day and Top Picks”, or IOTD/TP, is a long-running system to promote beautiful, interesting, peculiar, or otherwise amazing astrophotographs, with a focus on technical excellence. Learn more.

Submitted The date and time when you submitted this image for IOTD/TP consideration.	...
Views by Submitters (available since September 19th, 2023) Every image is assigned to 50% of available Submitters. In the event that at least 80% of them don't view the image before its time in the IOTD/TP process expires, it's assigned to the other 50% of Submitters and the process begins anew.
Promotions by Submitters When 3 distinct Submitters promote the image, it moves on to the next stage of the process: evaluation for Top Pick status. This requirement, in addition to anonymization of images and distribution to only a subset of them, prevents biases and ensures that the best images are selected.
Promotions by Reviewers When 3 distinct Reviewers promote the image, it moves on to the next stage of the process: evaluation for IOTD status.
Early dismissal Staff members have a lot of images to inspect on a daily basis, and they can dismiss images if they believe they don't meet the requirements for IOTD/TP selection. If an image is dismissed 5 times, it's removed from the process. This streamlines the process and ensures that any bias present in promotions could be overruled by other staff members.
